PISA - PISA More than half a million 15-year-olds took part in the OECD’s latest global education survey, known as PISA. The main focus was on science, an increasingly important part of our economic and social lives. You can also watch this video in Spanish. OECD PISA Webinar Series
Interactive Features The Spectrum of Neglect: Four Types of Unresponsive Care Using science as a guide, this interactive chart delineates four types of diminished responsiveness and their consquences in order to provide a useful framework for developing more effective strategies to protect vulnerable children from this complex challenge. The four short video clips below, each under a minute in length, are excerpts from the 6-minute video InBrief: The Science of Neglect. View interactive chart >>

The Neuroplasticity Phenomenon of Kindling Kindling; a model of focal epilepsy (last updated July 2006) A page from: Eric Hargreaves'Page O'Neuroplasticity As the name "Kindling" suggests, a small spark applied to tinder will ignite a flame that eventually can grow into a roaring bonfire. Similarly, a small electrical stimulus, just large enough to trigger a brief "afterdischarge" or burst of epileptiform activity, if repeatedly applied, will eventually generate seizures that can lead to fully generalized behavioral convulsions. As such, kindling is one of the best models of secondary generalized temporal lobe epilepsy, and much of our understanding of how epilepsy works comes from the study of kindling. Discovery As in much of science, kindling was stumbled upon by accident, but also as in much of science, the significance and potential of the phenomena was instantly recognized and pursued in its own right.
Pre-K Depression Linked to Changes in Brain Activity By Rick Nauert PhD Senior News Editor Reviewed by John M. Grohol, Psy.D. on July 2, 2013 New research provides the earliest evidence yet of changes in brain function in very young children with depression. Using functional magnetic resonance imaging (fMRI), researchers from Washington University School of Medicine in St. Louis discovered a key brain structure that regulates emotions works differently in preschoolers with depression compared with their healthy peers. Investigators say the findings could lead to ways to identify and treat depressed children earlier in the course of the illness, potentially preventing problems later in life.
Connections in the brains of young children strengthen during sleep, CU-Boulder study finds While young children sleep, connections between the left and the right hemispheres of their brain strengthen, which may help brain functions mature, according to a new study by the University of Colorado Boulder. The research team—led by Salome Kurth, a postdoctoral researcher, and Monique LeBourgeois, assistant professor in integrative physiology—used electroencephalograms, or EEGs, to measure the brain activity of eight sleeping children multiple times at the ages of 2, 3 and 5 years. “Interestingly, during a night of sleep, connections weakened within hemispheres but strengthened between hemispheres,” Kurth said. Scientists have known that the brain changes drastically during early childhood: New connections are formed, others are removed and a fatty layer called “myelin” forms around nerve fibers in the brain. The growth of myelin strengthens the connections by speeding up the transfer of information.
ADHD medication may be overprescribed in the U.S. Nearly 5 million privately insured Americans used a medication to treat attention deficit hyperactivity disorder (ADHD) in 2012, a 35% increase from 2008, according to an analysis from Express Scripts released this month. ADHD diagnoses and drug treatment are at “questionable levels” in the U.S., the authors suggested, further noting that the disease may have become a “go-to diagnosis” that masks other problems, like mood or anxiety disorders. Spending on ADHD medications rose 14.2% in 2012, which the report says is the greatest increase seen among any traditional drug category.
Inside the Letterbox: How Literacy Transforms the Human Brain Editor’s note: Few issues are as important to the future of humanity as acquiring literacy. Brain-scanning technology and cognitive tests on a variety of subjects by one of the world’s foremost cognitive neuroscientists has led to a better understanding of how a region of the brain responds to visual stimuli. The results could profoundly affect learning and help individuals with reading disabilities Although I find the diversity of the world’s writing systems bewildering, there is a striking regularity that remains hidden. Whenever we read—whether our language is Japanese, Hebrew, English, or Italian—each of us relies on very similar brain networks.1 In particular, a small region of the visual cortex becomes active with remarkable reproducibility in the brains of all readers (see figure 1).
The Most Dangerous Word in the World If I were to put you into an fMRI scanner—a huge donut-shaped magnet that can take a video of the neural changes happening in your brain—and flash the word “NO” for less than one second, you’d see a sudden release of dozens of stress-producing hormones and neurotransmitters. These chemicals immediately interrupt the normal functioning of your brain, impairing logic, reason, language processing, and communication. In fact, just seeing a list of negative words for a few seconds will make a highly anxious or depressed person feel worse, and the more you ruminate on them, the more you can actually damage key structures that regulate your memory , feelings, and emotions. You’ll disrupt your sleep , your appetite , and your ability to experience long-term happiness and satisfaction.
Dr. Ronald Ricker and Dr. Venus Nicolino: The Over-Prescribing of Psychoactive Drugs to Children: A Scourge of Our Times Today, the administration of psychoactive drugs to children (6-17) is all too common and growing at an alarming rate. These drugs often cause the opposite of the intended effect, often condemning children to a life of misery and ill health. The prescription of these drugs is said to treat "chemical imbalances" which were said to cause ADHD, Depression and Bi-polar disorder. It turns out, however, that what we were calling "disease-causing chemical imbalances," is simply incorrect .
